The method includes the transfer breeding of maintainer line, sterile line and restore line; breeding of superior hybrid rape combination with the sterile line or restore line with wax powder-free genetic marker; separating male and female parent and eliminating non-parent plant according to the marker while breeding and fast identifying the hybrid rate after collecting the seed and according to whether there is wax powder genetic marker or not; and eliminating sterile line micropowder self-crossing plant and other false hybrid plant during the seedling period of the F1 hybrid production to ensure the safety of rape hybrid. The present method can solve the difficult problem of existing sterile plant in cabbage type rape hybrid.
